By now, we all know that, inexplicably, this is not available on the state-of-the-art 2019 QX50. All the reviews say "not yet". Do you think that means that the system could be upgraded or just that newer models may be equipped with it? The HUD is a nice feature but, in my opinion, it becomes really useful when using navigation. And I definitely prefer Waze to the Sirius traffic. I wonder if Waze would even work with the HUD anyway with Android Auto.
